JAMES HENRY ASHWELL, OF NEW BASFORD, ENGLAND.

MACHINE FOR DYEING- HANKS.

Specification of Letters Patent.

Patented Jan. 12, 1909.

Application filed October 12, 1907. Serial No. 397,036.

To all whom it may concern:

Be it known that I, JAMES HENRY Asrr WELL, a subject of the King ofGreat Britain, and resident of Radford Road, New Basford, Nottingham,England, dyer and bleacher, have invented new and useful Improvements inMachinery for Dyeing Hanks, of which the following is a specification.

A machine for dyeing hanks embodying the present invention comprises atank or cistern containing the dye liquor. In connection with thisvessel are arranged a pair of endless chains traveling partly in andpartly out of the liquor. These chains carry the dye sticks whereon thehanks to be dyed are hung. The dye sticks are inserted at suitableintervals into the links of the chains in such a manner that they aredetachable when required but will not come out of position so long asthey are desired to remain. To this end one of the chains is providedwith sockets into which the sticks may be thrust endwise and the otherchain has sockets into which the ends of the sticks are thrusttransversely. The sockets are so contrived that when the sticks areinserted therein and partly rotated they will remain until purposelyremoved. The chains are mounted on sprocket wheels keyed upon shaftswhich are supported on a movable frame. Means are provided for raisingand lowering the said frame and the chains and the dye sticks therewithwhen required. One of the sprocket wheel shafts is driven by anysuitable means from any convenient source of power.

The hanks are hung on the sticks before the latter are placed in thesockets in the endless chains and while the framing which supports thechains is in its raised position. When the dye sticks are loaded theframing is lowered until the lower portion of the chains is submerged 5or 6 inches in the dye liquor. The chains are then driven and the hanksare drawn round and round through the liquor until the operation iscomplete.

In the accompanying drawings, Figure 1 represents the subject of thisinvention in side elevation, Fig. 2 is a plan view of the chain ofdyeing sticks and frame which supports the same, Fig. 3 is an end view,and Figs. 4 and 5 show detached links of the endless chains whichsupport the dyeing sticks.

a is the bark or cistern containing the dye liquor.

b is a frame supported by links 0 pendent from cords cl which are woundon drums eon the overhead shaft f. This shaft f has also the drum 9 forwinding up the cord h of the balance weight 2' which cord passes overthe pulley j.

7c is a grooved pulley and Z an endless cord thereon by means of whichthe shaft f may be rotated in either direction. The frame 6 carriesbearings for the shafts m n and 0 upon which are mounted wheels 79 p, gQ and r r for the endless chains 8 and t. One of these chains is builtup of links a (see Fig. l) and the other of links '0 (see Fig.

The hanks to be dyed are strung on sticks to having rounded and D shapedends. The rounded ends are inserted in the round holes of the links awhile the opposite D shaped ends are inserted in the clips of the links4). l/Vhen thus inserted and rotated a quarter turn the sticks willremain until intentionally removed. The sticks with the hanks thereonare placed in position in the chains when the frame is in the raisedposition of Figs. 1 and 3 in which position the chains may be made toadvance by means of the hand wheel 00 keyed on the shaft m. When thesticks are loaded the frame 7) is lowered by turning the shaft f in theproper direction until the base of the triangular path of the chain issubmerged in the dye liquor to the desired extent. (See dotted positionof Fig. 1.) In this position the spur wheel y on the shaft engages withthe pinion 2 indicated by dotted and drawn lines respectively in Figs. 1and 3 which pinion is driven in any convenient way. By means of thisgearing the chain of dye sticks is caused to travel and draw the hankscarried thereby through the liquor and around the whole triangular pathfollowed by the chain. In this way the operation of hand dipping isclosely imitated and work of equal quality produced. At the same timethe output of the machine is far greater than that of hand labor.

1 are guide rods fitted to the frame I), which guide rods slide in guidepillars 2 thereby steadying the frame in its upward and downwardmovements.

When the frame is raised ready access to the bark at for cleaning thesame or renewing the dye liquor is provided.

That I claim as my invention and desire to secure by Letters Patentis 1. An apparatus for dyeing hanks, comprising a tank, a frame locatedabove the tank, means for raising and lowering the frame, a pair ofcontinuous chains carried by the frame, means for causing said chains totravel in a triangular path and dyeing sticks detachably arranged in thechains.

2. An apparatus for dyeing hanks, comprising a tank, a frame locatedabove the tank, a counterweight and mechanism for raising and loweringthe frame, a pair of continuous chains carried by the frame, dye-9o9,51a a ing sticks detachably arranged in the chains, means forautomatically locking said sticks in osition and means for causing saidchains to travel in a triangular path.

In testimony whereof I have signed my name to this specification in thepresence of tWo subscribing Witnesses.
